USE AT YEAGER AIRPORT. I built this on PC and am not sure if it works on mobile. Once you are at yeager hit the accelerator key. If done correctly it will nosedive into the water in between 50,000MPH-55,000MPH. If not done correctly it will "fly" across the map for about 10 seconds. Just try again until it nosedives immediatly and watch the speedometer carefully for a max speed. I also made an 80,000MPH dragster but I am holding it back from the public currently. I am pretty sure I stumbled upon the perfect dragster design. Every time I tweak anything by even .1 it does not work near as good. Thanks as always, and have an awesome day building! PLEASE UPVOTE 4 MORE.
